Bimetric gravity and two-component fluid in the AdS/CFT correspondence

Understand

We study bimetric gravity through the context of the AdS/CFT correspondence, especially, in the first order hdrodynamic limit.

• If we put pure general relativity as a bulk field, the boundary field theory is interpreted as fluid of the N = 4 supersymmetric Yang-Mills plasma.
• The transport coefficients of this plasma are computed via the AdS/CFT correspondence.
• Then, we prepare a pair of gravitational fields on the bulk side and let them interact.
